A jail official found Jonathan Koppenhaver, 32, unresponsive on the floor of his cell Tuesday with linen around his neck and a suicide note in the room, News 3 reports. Koppenhaver, also known as War Machine, is accused of beating Christy Mack in August. He was reportedly in talks for a potential plea deal.

Prior to the suicide attempt, Koppehaver defended himself in a series of tweets.

The cops will never give me fair play, never believe me. Still deciding what to do but at the end of the day it's all just heart breaking.
